REGISTRATION RIGHTS

(a) file with the Commission one or more shelf or other registration statements on Form S-1 or such other form under the Securities Act then available to PEG Inc. providing for the resale by the Holders of all or a portion of the Registrable Shares held by such Holders in one or more separate public offerings or from time to time pursuant to Rule 415 of the Securities Act, if permitted by such form (including the Prospectus, any amendments and supplements to such registration statement or Prospectus, including pre- and post-effective amendments, all exhibits thereto, and all material incorporated by reference or deemed to be incorporated by reference, if any, in any such registration statement, the “Mandatory Registration Statement”); and/or (b) file in one or more Eligible Jurisdictions one or more base shelf prospectuses under NI 44-102 (including, as applicable, such other documents comprising the Canadian Prospectus of which the base shelf prospectus is a part, a “Mandatory Canadian Shelf Prospectus”) qualifying the Registrable Shares for public distribution in each such Eligible Jurisdiction. If PEG Inc. has an effective Mandatory Registration Statement on Form S-1 under the Securities Act and becomes eligible to use Form S-3 or such other short-form registration statement form under the Securities Act, PEG Inc. shall promptly give notice of such eligibility to the Holders and may, in its sole discretion, convert such Mandatory Registration Statement on Form S-1 to a registration statement on Form S-3 or such other short-form registration statement by means of a post-effective amendment or otherwise, unless the Holders notify PEG Inc. within 10 Business Days of receipt of the PEG Inc. notice that such conversion would interfere with its distribution of Registrable Shares already in progress and provides a reasonable explanation therefor, in which case PEG Inc. will delay the conversion of the Mandatory Registration Statement for a reasonable time after receipt of the first such notice, not to exceed 30 days in the aggregate.

(b) Effectiveness and Scope. PEG Inc. shall use its reasonable best efforts to cause the Mandatory Registration Statement to be declared effective by the Commission and/or a final receipt to be issued for the Mandatory Canadian Shelf Prospectus by the Principal Canadian Regulator within 120 days following the Demand Date, and to remain effective until, in the case of a Mandatory Registration Statement, the date on which all shares of Common Stock in respect thereof cease to be Registrable Shares and, in the case of a Mandatory Canadian Shelf Prospectus, the earlier of the date on which the Holders no longer hold any Registrable Shares and 25 months from the date on which the receipt is issued. The Mandatory Registration Statement and/or the Mandatory Canadian

Shelf Prospectus shall provide for the resale from time to time, and pursuant to any method or combination of methods legally available (including an Underwritten Offering, a direct sale to purchasers, a sale through brokers or agents, or a sale over the internet), by the Holders.

(c) Underwriting. If one or more Holders propose to conduct an Underwritten Offering under the Mandatory Registration Statement or the Mandatory Canadian Shelf Prospectus, the Holder holding a majority of the Registrable Shares to be sold in such Underwritten Offering shall advise PEG Inc. of the managing underwriters for such proposed Underwritten Offering. In such event, PEG Inc. shall enter into an underwriting agreement in customary form with the managing underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Article V and shall take all such other reasonable actions as are requested by the managing underwriter in order to expedite or facilitate the registration and/or qualification and the disposition of the Registrable Shares included in such Underwritten Offering; provided, however, that PEG Inc. shall not be required to conduct more than three such Underwritten Offerings during any 365 day period; provided, further, that PEG Inc. shall not be required to conduct any such Underwritten Offering unless the anticipated gross proceeds from such Underwritten Offering are at least $25 million; provided, further, that PEG Inc. shall be required to cause appropriate officers of PEG Inc. or its Affiliates to participate in a “road show” or similar marketing effort being conducted by such underwriter with respect to such Underwritten Offering only if the Holders participating in the Underwritten Offering reasonably anticipate gross proceeds from such Underwritten Offering of at least $75 million; provided, further, that PEG Inc. shall not be required to cause such officers of PEG Inc. or its Affiliates to participate in a “road show” or similar marketing effort being conducted by such underwriter with respect to such Underwritten Offering more than twice in a 365 day period. Holders proposing to distribute Registrable Shares through such Underwritten Offering shall enter into an underwriting agreement in customary form with the managing underwriters selected for such Underwritten Offering and complete and execute any questionnaires, personal information forms, powers of attorney, submissions to jurisdiction, certificates, undertakings, declarations, notices, indemnities, securities escrow agreements, and other documents reasonably required under the terms of such underwriting (including, without limitation, any documents required under the Securities Act or applicable Canadian Securities Laws), and furnish to PEG Inc. such information in writing as PEG Inc. may reasonably request for inclusion in the Mandatory Registration Statement and/or Mandatory Canadian Shelf Prospectus. Notwithstanding any other provision of this Agreement, with respect to an Underwritten Offering pursuant to a Mandatory Registration Statement or a Mandatory Canadian Shelf Prospectus, if the managing underwriters determine in good faith that marketing factors require a limitation on the number of shares to be included in such Underwritten Offering, then the managing underwriters may exclude shares (including Registrable Shares) from the Underwritten Offering, and any shares included in the Underwritten Offering shall be allocated to the Holders to the extent of its requested amount of Registrable Shares to be included in the Underwritten Offering.

2.2 Piggyback Registration Rights. (a) If, after the date hereof, PEG Inc. proposes (i) to file a registration statement under the Securities Act providing for a public offering of PEG Inc.’s equity securities, other than a registration statement on Form S-8 or Form S-4 or any similar form hereafter adopted by the Commission as a replacement therefor (including the Prospectus, any amendments and supplements to such registration statement or Prospectus, including pre- and post-effective amendments, all exhibits thereto, and all material incorporated by reference or deemed to be incorporated by reference, if any, in such registration statement, the “Piggyback Registration Statement”); and/or (ii) to file a Canadian Prospectus providing for a public offering of PEG Inc.’s equity securities in one or more Eligible Jurisdictions (a “Piggyback Canadian Prospectus”), or (iii) conduct an Underwritten Offering pursuant to a Piggyback Registration Statement or a Piggyback Canadian Prospectus, PEG Inc. will notify the Holders of the proposed filing and the Holders shall be given an opportunity to include in the public offering provided for under such Piggyback Registration Statement or Piggyback Canadian Prospectus or in the Underwritten Offering, as applicable, all or any part of their Registrable Shares; provided, however, that, except as set forth below, the Holders shall not be given an opportunity to include Registrable Shares in any Underwritten Offering to the extent that PEG Inc. has been advised by the managing underwriter of such Underwritten Offering that the inclusion of any Registrable Shares for sale for the benefit of the Holders will have a materially adverse effect on the price, timing, marketing, or distribution of the Common Stock. If any Holder has an Affiliate who is an officer or director of PEG Inc., within 10 Business Days after delivery of the above-described notice by PEG Inc., such Holder has the right to notify PEG Inc. in writing of its intention to include Registrable Shares in the public offering provided for under such Piggyback Registration Statement or Piggyback Canadian Prospectus or in the Underwritten Offering, as applicable, and, in such notice, shall inform PEG Inc. of the number of Registrable Shares that such Holder wishes to so include, as applicable, and provide, as a condition to such inclusion, such information regarding the Holder and their Registrable Shares as is required pursuant to Regulation S-K promulgated under the Securities Act and/or applicable Canadian Securities Laws to effect the registration and/or qualification of the Registrable Shares; provided, however, that if no Holder has an Affiliate who is an officer or director of PEG Inc., such Holder shall provide such notice within three Business Days (or one Business Day in the case of an “overnight” offering or “bought deal”) after delivery of the above-described notice by PEG Inc. If such written notification of a Holder’s intent to include Registrable Shares in the public offering provided for under such Piggyback Registration Statement or Piggyback Canadian Prospectus or in the Underwritten Offering, as applicable, is not received by PEG Inc. within the applicable time-frames specified in the immediately preceding sentence, such Holder shall have no right to so include any Registrable Shares. Inclusion of any Registrable Shares in such Piggyback Registration Statement will not affect the inclusion of such Registrable Shares in the Mandatory Registration Statement until such Registrable Shares have been sold under the Piggyback Registration Statement, at which time PEG Inc. may remove from the Mandatory Registration Statement such Registrable Shares.

(b) Right to Terminate Piggyback Registration. At any time, PEG Inc. may terminate or withdraw any Piggyback Registration Statement or Piggyback Canadian Prospectus referred to in this Section 2.2, and without any obligation to a Holder whether or not such Holder has elected to include Registrable Shares in such registration or qualification, as applicable. PEG Inc. may suspend the effectiveness and use of any Piggyback Registration Statement or Piggyback Canadian Prospectus at any time for an unlimited amount of time whether or not a Holder has elected to include Registrable Shares in such registration or qualification, as applicable.

(c) Underwriting. Any notice provided to the Holders by PEG Inc. pursuant to Section 2.2(a) in connection with an Underwritten Offering shall advise the Holders of the managing underwriters for any Underwritten Offering proposed under the Piggyback Registration Statement or Piggyback Canadian Prospectus. A Holder’s right to include Registrable Shares in any Piggyback Registration Statement or Piggyback Canadian Prospectus pursuant to this Section 2.2 shall be conditioned upon participation in such Underwritten Offering and the inclusion of its Registrable Shares in the Underwritten Offering to the extent provided herein. A Holder, if distributing its Registrable Shares through such Underwritten Offering, shall enter into an underwriting agreement in customary form with the managing underwriters selected for such Underwritten Offering and complete and execute any questionnaires, personal information forms, powers of attorney, submissions to jurisdiction, certificates, undertakings, declarations, notices, indemnities, securities escrow agreements, and other documents reasonably required under the terms of such underwriting (including, without limitation, any documents required under the Securities Act or applicable Canadian Securities Laws), and furnish to PEG Inc. such information in writing as PEG Inc. may reasonably request for inclusion in the Registration Statement or Canadian Prospectus. Notwithstanding any other provision of this Agreement, with respect to an Underwritten Offering pursuant to a Piggyback Registration Statement or a Piggyback Canadian Prospectus, if the managing underwriters determine in good faith that marketing factors require a limitation on the number of shares to be included in such Underwritten Offering, then the managing underwriters may exclude shares (including Registrable Shares) from the Underwritten Offering, and any shares included in the Underwritten Offering shall be allocated first, to PEG Inc., and second, to the Holders, and third, to any other Person included in such Underwritten Offering. If a Holder disapproves of the terms of any Underwritten Offering pursuant to a Piggyback Registration Statement or a Piggyback Canadian Prospectus, such Holder may elect to withdraw therefrom by written notice to PEG Inc. and the underwriter, delivered at least 10 Business Days before the effective date of the Piggyback Registration Statement or at any time prior to execution of a definitive underwriting agreement in connection with an Underwritten Offering pursuant to a Piggyback Registration Statement.

(d) Hold-Back Agreement. By electing to include Registrable Shares in an Underwritten Offering pursuant to a Piggyback Registration Statement or a Piggyback Canadian Prospectus, a Holder shall be deemed to have agreed not to effect any sale or distribution of securities of PEG Inc. of the same or similar class or classes of the securities included in the Registration Statement or Canadian Prospectus or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the Securities Act, during such periods as reasonably requested (but in no event longer than 30 days before or 90 days following the pricing of such Underwritten Offering by the representatives of the underwriters).

(e) Mandatory Registration not Impacted by Piggyback Registration Statement. PEG Inc.’s obligation to file any Mandatory Registration Statement or Mandatory Canadian Shelf Prospectus shall not be affected by the filing or effectiveness of the Piggyback Registration Statement or Piggyback Canadian Prospectus, as applicable.

2.4 Expenses. PEG Inc. shall pay all Registration Expenses in connection with the registration of the Registrable Shares pursuant to this Agreement. A Holder, if participating in a registration or qualification pursuant to this Section 2.3, shall bear all discounts and commissions payable to underwriters or brokers and all transfer taxes, if any, in connection with a registration of its Registrable Shares pursuant to this Agreement and any other expense of such Holder not specifically allocated to PEG Inc. pursuant to this Agreement relating to the sale or disposition of its Registrable Shares pursuant to any Registration Statement or Canadian Prospectus. Nothing herein shall require PEG Inc. to pay any fees, costs, or disbursements of or relating to counsel for a Holder unless required pursuant to Section 5.3.

2.5 No Additional Demand Registration Rights. Unless otherwise consented to by the Holders, which consent may be unreasonably withheld, PEG Inc. shall not grant to any other Person a demand registration right to register Common Stock for sale to the public in an Underwritten Offering or in a continuous offering under Rule 415 of the Securities Act or under NI 44-102.

2.6 MJDS. Notwithstanding anything contained in this Article II or in Section 3.2, in the event that PEG Inc. is required hereunder to qualify any Registrable Shares for public distribution in an Eligible Jurisdiction pursuant to the applicable requirements and procedures set forth in the MJDS Rule, the terms and conditions hereof shall apply, mutatis mutandis.

2.7 Additional Shares. For the avoidance of doubt, PEG Inc., at its option, may register for sale or resale, as applicable, under a Mandatory Registration Statement or a Canadian Prospectus filed pursuant to this Agreement or otherwise, any number of unissued shares of Common Stock (or any other securities of PEG Inc.) or any shares of Common Stock (or other securities of PEG Inc.) owned by any security holder of PEG Inc. (other than the Holders); provided, that, except as otherwise provided herein, in no event shall the inclusion of such securities on any such Registration Statement or a Canadian Prospectus reduce the amount offered for the account of the Holders in any Underwritten Offering at the request of the Holders pursuant to Section 2.1 hereof.

ARTICLE V

PEG Inc. shall notify the Holders promptly of the institution, threat, or assertion of any claim, proceeding (including any governmental investigation), or litigation which it shall have become aware in connection with the matters addressed by this Agreement which involves PEG Inc. or a Purchaser Indemnitee. The indemnity provided for herein shall remain in full force and effect regardless of any investigation made by or on behalf of any Purchaser Indemnitee.

5.2 Indemnification by the Holders. In connection with any Registration Statement or Canadian Prospectus in which the Holders are participating, the Holders agree to indemnify and hold harmless PEG Inc., each Person who controls PEG Inc. within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, and the respective officers, directors, partners, members, representatives, employees, and agents of such Person or Controlling Person to the same extent as the foregoing indemnity from PEG Inc. to each Purchaser Indemnitee, but only with reference to (a) untrue statements or omissions or alleged untrue statements or omissions made in reliance upon and in strict conformity with information relating to the Holders furnished to PEG Inc. in writing by the Holders expressly for use in any Registration Statement, Prospectus or Canadian Prospectus, any amendment or supplement thereto, or any preliminary Prospectus or preliminary Canadian Prospectus and (b) any sales by the Holders after the delivery by PEG Inc. to the Holders of a Suspension Notice and before the delivery by PEG Inc. of an End of Suspension Notice. The liability of the Holders pursuant to clause (a) of the immediately preceding sentence shall in no event exceed the net proceeds received by the Holders from sales of Registrable Shares giving rise to such obligations. If the Holders elect to include Registrable Shares in an Underwritten Offering, the Holders shall be required to agree to such customary indemnification provisions as may reasonably be required by the underwriter in connection with such Underwritten Offering.

5.3 Indemnification Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim, or demand shall be brought or asserted against any Person in respect of which indemnity may be sought pursuant to Section 5.1 or 5.2, such Person (the “Indemnified Party”), shall promptly notify the Person against whom such indemnity may be sought (the “Indemnifying Party”), in writing (to the extent legally advisable) of the commencement thereof (but the failure to so notify an Indemnifying Party shall not relieve it from any Liability which it may have under this Article V, except to the extent the Indemnifying Party is materially prejudiced by the failure to give notice), and the Indemnifying Party, upon request of the Indemnified Party, shall retain counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party and any others the Indemnifying Party may reasonably designate in such proceeding and shall assume the defense of such proceeding and pay the fees and expenses actually incurred by such counsel related to such proceeding. Notwithstanding the foregoing, in any such proceeding, any Indemnified Party may retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party, unless (a) the Indemnifying Party and the Indemnified Party shall have mutually agreed in writing to the contrary, (b) the Indemnifying Party failed within a reasonable time after notice of commencement of the action to assume the defense and employ counsel reasonably satisfactory to the Indemnified Party, (c) the Indemnifying Party and its counsel do not pursue in a reasonable manner the defense of such action, or (d) the named parties to any such action (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, or any Affiliate of the Indemnifying Party, and such Indemnified Party shall have been reasonably advised by counsel that, either (x) there may be one or more legal defenses available to it which are different from or additional to those available to the Indemnifying Party or such Affiliate of the Indemnifying Party or (y) a conflict may exist between such Indemnified Party and the Indemnifying Party or such Affiliate of the Indemnifying Party, in which event the

Indemnifying Party may not assume or direct the defense of such action on behalf of such Indemnified Party, it being understood, however, that the Indemnifying Party shall not, in connection with any one such action or separate but substantially similar or related actions arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all such Indemnified Parties, which firm shall be designated in writing by those Indemnified Parties who sold a majority of the Registrable Shares sold by all such Indemnified Parties under the particular Registration Statement and any such separate firm for PEG Inc., the directors, the officers and such control Persons of PEG Inc. as shall be designated in writing by PEG Inc. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld or delayed, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Party agrees to indemnify any Indemnified Party from and against any Liability by reason of such settlement or judgment to the extent provided in this Article V without reference to this sentence. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all Liability on claims that are the subject matter of such proceeding.

5.4 Contribution. If the indemnification provided for in Section 5.1 or 5.2 is for any reason held to be unavailable to an Indemnified Party in respect of any Liabilities referred to therein (other than by reason of the exceptions provided therein) or is insufficient to hold harmless a party indemnified thereunder, then each Indemnifying Party under such sections, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Liabilities in such proportion as is appropriate to reflect the relative fault of the Indemnified Party on the one hand and the Indemnifying Parties on the other in connection with the statements or omissions that resulted in such Liabilities, as well as any other relevant equitable considerations. The relative fault of PEG Inc., on the one hand, and any Purchaser Indemnitees, on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by PEG Inc. or by such Purchaser Indemnitees and the parties” relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

5.5 Contribution Procedures. The parties agree that it would not be just and equitable if contribution pursuant to this Article V were determined by pro rata allocation (even if such Indemnified Parties were treated as one entity for such purpose), or by any other method of allocation that does not take account of the equitable considerations referred to in Section 5.4. The amount paid or payable by an Indemnified Party as a result of any Liabilities referred to in Section 5.4 shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses actually incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Article V, in no event shall a Purchaser Indemnitee be required to contribute any amount in excess of the amount by which proceeds received by such Purchaser Indemnitee from sales of Registrable Shares exceeds the amount of any damages that such Purchaser Indemnitee has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission

or alleged omission. For purposes of this Article V, each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) the Holders shall have the same rights to contribution as the Holders, as the case may be, and each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) PEG Inc., and each officer, director, partner, member, employee, representative, agent, or manager of PEG Inc. shall have the same rights to contribution as PEG Inc. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit, or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Article V or otherwise, except to the extent that any party is materially prejudiced by the failure to give notice. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act), shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

5.6 Additional Liability. The indemnity and contribution agreements contained in this Article V will be in addition to any Liability which any Indemnifying Party may otherwise have to any Indemnified Party referred to above. Each Purchaser Indemnitee’s obligations to contribute pursuant to this Article V are not joint but are several in the proportion that the number of share of Common Stock sold by such Purchaser Indemnitee bears to the number of share of Common Stock sold by all Purchaser Indemnities.

5.7 Conflicts with Underwriting Agreements. Notwithstanding the other provisions of this Article V, to the extent that the provisions on indemnification and contribution contained in an underwriting agreement entered into in connection with an Underwritten Offering are in conflict with the foregoing provisions, the provisions of such underwriting agreement shall control.

MISCELLANEOUS

7.1 Construction. The parties have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties and no presumption or burden of proof will arise favoring or disfavoring any party because of the authorship of any provision of this Agreement. Any reference to any federal, state, provincial, local, or foreign law will be deemed also to refer to such law as amended and all rules and regulations promulgated thereunder, unless

the context requires otherwise. Any reference to any contract or agreement (including schedules, exhibits, and other attachments thereto), including this Agreement, will be deemed also to refer to such agreement as amended, restated, or otherwise modified, unless the context requires otherwise. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context requires otherwise. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. Where this Agreement states that a party “will” or “shall” perform in some manner or otherwise act or omit to act, it means that such party is legally obligated to do so in accordance with this Agreement. The captions, titles, and headings included in this Agreement are for convenience only and do not affect this Agreement’s construction or interpretation. Any reference to an Article, Section or Schedule in this Agreement shall refer to an Article or Section of, or Schedule to, this Agreement, unless the context otherwise requires. Other than with respect to Article V, this Agreement is for the sole benefit of the parties and does not, and is not intended to, confer any rights or remedies in favor of any Person (including any employee or shareholder of any Holder or PEG Inc.) other than the parties.

7.2 Entire Agreement. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and thereof and supersedes (a) all prior oral or written proposals or agreements, (b) all contemporaneous oral proposals or agreements, and (c) all previous negotiations and all other communications or understandings between the parties, in each case with respect to the subject matter hereof and thereof.

7.5 Severability. If any term or other provision of this Agreement shall be determined by a court, administrative agency, or arbitrator to be invalid, illegal, or unenforceable, such invalidity, illegality, or unenforceability shall not render the entire Agreement invalid.

Upon such determination that any term or other provision is invalid, illegal, or unenforceable, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent permitted under applicable Law.

7.6 Amendment. This Agreement may only be amended by a written agreement executed by both parties.

7.10 Waiver. A provision of this Agreement may be waived only by a writing signed by the party intended to be bound by the waiver. A party is not prevented from enforcing any right, remedy, or condition in the party’s favor because of any failure or delay in exercising any right or remedy or in requiring satisfaction of any condition, except to the extent that the party specifically waives the same in writing. A written waiver given for one matter or occasion is effective only in that instance and only for the purpose stated. A waiver once given is not to be construed as a waiver for any other matter or occasion. Any enumeration of a party’s rights and remedies in this Agreement is not intended to be exclusive, and a party’s rights and remedies are intended to be cumulative to the extent permitted by Law and include any rights and remedies authorized in Law or in equity.

7.11 Arbitration. All disputes and controversies which may arise out of or in connection with this Agreement and are not resolved through good faith negotiation shall be settled by binding arbitration in accordance with the provisions of Article VI of the Separation and Distribution Agreement.
